This article is about the evolutionary sequence. For the extensible c/4 diagonal spaceship, see Wing (spaceship).
"Wing" can additionally refer to a protruding lateral section of any spaceship, such as a group of switch engines supporting one side of a Cordership.

Wing is a common evolutionary sequence that stabilizes at generation 104 as a block and a glider. Its most common grandparent is traditionally referred to as block and glider, which is composed of two pre-blocks and has a lifespan of 106 generations. That pattern has a six-cell parent called nine, resembling an eater 1 with one tail cell missing. Nine can also be seen as a pre-block connected to a three-cell-long line.

Uses

In still lifes

Nine is a part of several still lifes, some of which are shown in the table below:

Object Population Other part
Integral sign 9 Pre-block
Tub with nine (prodigal) 10 Tub
Hook with nine (hooked integral) Hook
Cis-boat with nine 11 Boat
Trans-boat with nine
Long hook with nine Long hook
Hungry hat Unnamed
Cis-barge with nine 12 Barge
Trans-barge with nine
Beehive with nine Beehive
Claw with nine Claw
Cis-very long hook with nine Very long hook
Trans-very long hook with nine
Twelve loop Unnamed

Tails can often be replaced with nines. When the resulting still life is able to perform a eater 1 catalysis using the added nine, the resulting still life is referred to as being "hungry".

In oscillators

A nine is hassled by two eater 1s in a period-4 oscillator, confused eaters.

Like other common evolutionary sequences, wings can be hassled in various ways, such as in the p25 wing and block hassler[note 1][note 2] and p128 wing shuttle.

A full list is located at Wing hasslers.

Some oscillators, even if they're not wing hasslers, produce wings, such as Charity's p16, Beluchenko's other p37, and one of the p43 honey farm hasslers. Generation 7 of wing produces dot sparks, which can be useful, as it makes the oscillator a sparker.

In conduits

A number of conduits have been found to produce or accept a wing (abbreviated W) with reasonable clearance, such as PF35W, a wing-to-LWSS converter and WFx46H. A WSW-3 conduit[note 3] can be made by eating the extra block using a block or eater 1.

Notes

  1. ↑ Catagolue: p25 wing and block hassler
  2. ↑ An alternative version of this oscillator is shown in jslife with a different method of stabilization.[1] Nicolay Beluchenko found the simpler stabilization with two fumaroles later on.[2] However, it is unknown when or by whom this reaction was found.[3]
